Our Third Party Testing Bodies: LLOYDS BRITISH, ICAS, SGS
All Access Covers are manufactured in SMC
No inherent scrap value
Corrosion resistant
Impact and weather resistant
Uniqe multi-directional slip
lightweight meeting Manual Handling Regulations
Avatar SMC Performance index
Anti slip pattern
Avatar cover of composite access covers achieved a market leading Skid Resistance Value of 89
The table below has been developed from data collected by County
Surveyors Society and illustrates the acceptabable parameters when tested using the TRRL Pendulum Test in general accordance with BS667:part 1:1986
This test provides a slip resistance value(SRV) for each surface tested The higher value the greater slip resistance.
TRRL Pengulum Value | Condition Of Surface |
19 and below | Dangerous |
20-39 | Marginal |
40-74 | Satisfactory |
Adove75 | Excelient |
